Enter button on Android no longer auto presses Check

This app was lovely to use when the enter key automatically checked the answer, having that be 2 steps significantly reduces the efficiency of the app. 

Ideally I would see the app automatically check the answer without needing to press the enter key. The only issue with this would be if the answer is something like "ne" I think just ignoring "n" as an answer is a fine way to bodge it.
